CTLA-4 Antibody

CTLA-4 antibody is a type of immunotherapy that targets a specific protein called CTLA-4 on immune cells. Normally, CTLA-4 acts as a "brake" to slow down immune responses, which can sometimes prevent the immune system from attacking cancer cells effectively. The antibody blocks CTLA-4, releasing this brake and allowing the immune system to better recognize and fight tumors. This approach helps boost the body's natural defenses against cancer, making it a valuable tool in cancer treatment, especially for certain types like melanoma.
